Sloshing has many industry applications, namely in offshore engineering, aerospace, ship building, and manufacturing. simulation is essential to better understand the sloshing pattern consequently improve tank design reduce noise levels, stresses on structure, optimize baffle configurations arrangements. Thus, aim of this study determine effects perforated (porous) imperforate (solid) baffles p...

Abstract. An in-house Navier-Stokes multiphase VOF (Volume-Of-Fluid) solver is used to study sloshing phenomena in a partially filled rectangular tank subjected vertical sinusoidal excitation. The flow dynamics found be significantly affected by acceleration and forcing frequency. Specifically, when the strong excitation frequency low, exhibits more chaotic three-dimensional nature. Consequentl...

This paper describes a novel numerical model aiming at solving moving-boundary problems such as free-surface flows or fluid-structure interaction. This model uses a moving-grid technique to solve the Navier–Stokes equations expressed in the arbitrary Lagrangian-Eulerian kinematics. The discretization in space is based on the spectral element method. The coupling of the fluid equations and the m...

A machine learning technique is proposed to derive the damping rate functions in co-called single-dominant modal system describing resonant liquid sloshing a rectangular tank performing harmonic longitudinal motions. Its implementation demonstrated for steady-state (periodic) resonance waves when admits an analytical asymptotic solution depending on introduced functions. Recent experiments by B...

A behavioral syndrome exists when specific behaviors interact under different contexts. Zebrafish have been test subjects in recent studies and it is important to standardize protocols to ensure proper analyses and interpretations. In our previous studies, we have measured boldness by monitoring a series of behaviors (time near surface, latency in transitions, number of transitions, and darts) ...

We consider the problem of the active reduction of structural vibrations of a plane wing induced by the sloshing of large masses of fuel inside partly full tank. This study focuses on an experimental device composed of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid at the opposite free end.
